Astonishing! I hadn't come across this before - absolutely fascinating!

🚨 Breaking news for math enthusiasts: a blog post on a *single* lemma from a 2023 textbook! 📚😴 Apparently, you need a PhD just to understand the introduction. But don’t worry, the Fundamental Theorem of Galois Theory itself isn’t explained here, because who needs the main course when you can have a crumb? 🥖🙄

Lemma for the Fundamental Theorem of Galois Theory

I'm reading Artin's #GaloisTheory and I'm wondering if the #math exposition of the #matrix #determinant relying on homogeneity properties is related to the #BrunnMinkowski #inequality

I will check my handwritten notes when I'll be in Poland end of July but I remember that homogeneity played a role there.

This rambling is related to my struggle to understand the #BrascampLieb and #rearrangementInequality. Any hints much appreciated 🥹😅🙈😊
